BATH SPONGE.

Application filed July 29,

To @Zt 'w 7mm z't may con-cera: I

I, (lnoncn lfianrrnrnnn, a citizen of Canada, residing at 535 Sherbourne Street, in the city of Toronto, in the county of York, in the Province of Untario, Canada, have invented certain new and useful Improvements in Bath Sponges, of which the following is the specification.

My invention relates to improvements in bathk sponges and the object of the invention is to produce an article which will have all the advantages of an ordinary wash rag and yet none of its disadvantages, such as hardness, lack of resiliency and means for carrying a supply of water for ready application.

A still further object is to provide an article of this class having the advantages of a sponge and in which the rubbing surface is of such a character as will readily produce a glow on the body without liability of eX- coriation.

A still further object is to make a sanitary article, which after being used will quickly dry in order to keep it sweet and clean, and thereby make it always ready for packing for travelling.

A still further object is to make the article cheaply, so that it can `be sold for a reasonable market price.

A yet further object is to make the article compact and of a smooth surface from end to end, and insure that the ends themselves will be smooth and uniform.

To effect these objects I have provided my bath sponge with a sponge centre of rubber or other form of sponge or spongy material and a covering of a circularly knitted fabric preferably cotton machine knitted for cheapness, the fabric being knitted with a double thread for the major portion of its length and at each end with a single thread, such fabric being turned inside out, so that the projecting crosslike ribs forming the inner surface of the fabric will extend outwardly and form a rubbing surface. The single thread ends of the fabric are provided with draw strings, whereby they can be drawn up over the end of the sponge centre or core, and thereby form a close gripping contact smooth in contour as hereinafter more particularly explained.

as knitted previous to its application to the sponge.

In the drawings like characters of reference indicate corresponding parts in each figure.

l is the sponge core, which may be what is known as an open rubber sponge, such as is commonly used to-day. I, of course, do not wish to limit myself to this sponge as a natural sponge may be used with equal facility.

2 is the encompassing knitted covering, which is preferably knitted in a circular knitting machine for cheapness and with a double thread preferably of cotton cord or the like. As is usual in knitted fabric the outer surface is generally comparatively smooth, but the inner surface is necessarily formed with a cross ribbing 3. The ends of the fabric are knitted with a single thread so as to form the single thread ends 4, which are preferably provided with draw strings 5. The fabric is shown inside out in respect to the way in which it comes from the circular knitting machine, so that the ribs 3 eX- y tend crosswise and form an excellent rubbing surface.

It will be noticed that in Fig. 1 also the single thread ends are drawn together by the draw strings 5, which are suitably tied and inserted through the small openings in the ends so as not to expose them.

By such a single thread I am enabled to y make the end of my bath sponge smooth and uniform, so that such single thread ends closely hug the ends 'of the sponge.

I am aware that Sponges have been provided with a covering previous to my inevntion, but I do not know of any article of this class in which a sponge may be utilized and form the base or core of a wash rag in which there is provided as cheap a covering and one which has such advantages as that which I have devised.

lvl/That I claim as my invention is:

l. A bath device comprising a core of elastic absorbent material and a tubular knitted envelope formed with a double thread for the major portion of its length and with single thread ends, which are drawn in to hug the ends 'of the core.

2. A bath device comprising a core of elastic absorbent material and a tubular knitted envelope formed with a double thread for the major portion of its length and with single thread vends,` which are drawn in to Hug tlie ends of tiie core, the fabric being turned inside out so that the ribbed inner surface forms Athe outer sur- 5 face when encompassing the core.

3. A bath device comprising a core of elastic absorbent material, and a tubular envelope7 the intermediate portion of said envelope being oi sbst'antally greztterthickness than the end portions whereby the end 10 portions may be drawn in to tthe ends of the spontgecoreiwithout producing bulges.
